ADJUSTABLE HAlVIE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 699,482, dated May 6,1902.

Application filed October 14,1901. Serial No. 78,604. (No model.)

To ztZZ whont it 77LU/Z/ concern:

Be it known that I, FRANK J. BOYLE, a citizen of the United States,residing at Galveston, in the county of Galveston and State of Texas,have invented a new and useful Adjustable flame-Fastener, of which thefollow-- lower ends, and to provide a simple and com parativelyinexpensive device capable of detachably connecting the lower ends of apair of hames and adapted to permit the said hames to be adjustedlaterally to vary the distance between them.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is an elevation of a pair of hames constructedin accordance with this invention. Fig. 2 is a detail sectional View ofthe top of the hames, illustrating the manner of adjustably connectingtheir upper ends. Fig. 3 is a detail perspective view of the hingedconnecting-bars. Fig. 4 is a detail sectional view illustrating theconstruction of the adjustable telescoping sections. Figs. 5 and 6 aredetail views illustrating the construction of the hame-fasteners.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l 1 designate apair of hames composed of upper and lower sections 2 and3, capable of longitudinal adjustment to vary the length of the hames.The lower section 3 of each hame is tubular and receives'the lowerportion of the upper section 2, which is preferably solid, but which maybe of any desired construction. The lower section is preferably rein.

forced at its upper end by a collar 4, and it is provided with alongitudinal slot 5, extending downward from the collar and receivingaset-screw 6, mounted in a threaded perforation of the upper section 2and having a square head for engaging the lower section. The sections 2and 3 are preferably provided adjacent to the slot with marks arrangedat intervals to enable the sections to be acourately adjusted withoutmeasuring the distance with a rule or the like. The set-screw is adaptedto move freely in the longitudinal slot, and it is capable of securelyfastening the hames at any desired adjustment. The upper sections of thehames are curved inward, as shown, and are provided at their terminalswith sleeves 7, receiving the outer portions of hinged connecting-bars 8and provided with clamping-screws 9 for engaging the connecting-bars, asclearly illustrated in Fig. 2 of the accompanying drawings, whereby theham es are secured at the desired lateral adjustment. Theconnecting-bars,which are rectangular in cross-section, are provided attheir inner ends, which are enlarged, with eyes 10 and 11, receiving apintle 12, which preferably consists of a bolt, but which may be of anyother desired construction. The hinged connecting-bars are adapted toslide freely in the sleeves of the upper ends of the hames, which arecapable of lateral adj ustment without increasing or diminishing theirlength. The hinged joint also permits the hames to swing readily apart,and they are adapted for use in fire-engine houses, where the harness issuspended.

The lower ends of the lower sections of the hames are extended inwardhorizontally and have casings 13 and 14. adjustably secured to them forvarying the width of the hames at the bottoms thereof. The casings 13and 1-1 are provided with upper and lower sleeves 15 and 10, theuppersleeves having circular bores and conforming to the configurationof the lower sections of the hames, and the lower sleeves 16 areprovided with rectangular openings. The upper sleeves are provided witha plurality of perforations for the reception of screws 17 or othersuitable fastoning devices, and by changing the fastening devices fromone perforation to another the ham es may be varied in Width.

A bar 18 is secured by a transverse screw 19 or other suitable fasteningdevice in the lower sleeve of the casing'lt, and it extendslongitudinally of the lower portions of the hames and is provided atopposite sides with recesses 20, receiving resilient catches 21. Theresilient catches consist of resilient .the casing 13, whereby the hamesare securely shanks secured at their inner ends to the bar l8 andprovided at their outer ends with laterally-extending engaging headsadapted to project outward beyond the bar and engage the adjacent sideedges of the lower sleeve of locked and are effectually prevented frombecoming accidentally nnfastened through any jar or vibration incidentto horse motion or the like. The heads of the catches are adapted to bereadily compressed or forced inward to unfasten the hames.

What I claim is- The combination of the hames;the casings
